I have known about this issue a while, ever since the choice was made to
consider all of dynamic to be non-OMP scalible. The problem with dynamic
is that all format SHARE the same code, and since each thread can be at
any point within running script for a range of values, then each of the
sub functions within dyna also has to be supportive of OMP. So it is
pretty much an all or nothing.

This is probably the correct way to proceed, and make sure that format can
also prepare/split any $dynamic_17$ back into it's native hash type.
